Cofounder of CodeCombat and Skritter, experimenter of self, student of rationality, hacker of motivation. One summer I wrote a book, learned to skateboard and throw knives and lucid dream, trained for a marathon and other feats, learned a ton of Chinese.

What a crazy weekend! We launched our beta on Friday morning by posting to afewsubreddits hoping to pick up a few more interested users who could play through our levels as we started to release new ones with the level editor we just finished. But we were not prepared for how many people would come check it out. We stayed #1 on all three subreddits for over a day, amassing 1466 points, 384 comments, and far too many players for our real-time multiplayer server to handle (forcing us to shut off the multiplayer and all server code synchronization). And that's all before we were crushed the next day by what appeared to our beleaguered Scott as all of Brazil, or at least every Brazilian on Facebook. (Olá!)

With all the chaos trying to keep the server up and the bugs down, we slept little and prepared for the next day's Startup School even less. We had been tapped for on-stage Y Combinator office hours with Paul Graham and Sam Altman. We watched a video of previous on-stage YC office hours and concluded that "office hours" really meant "eight minutes of two of the smartest startup guys in the world demolishing your idea in front of 1700 entrepreneurs and a live video stream".

Fortunately for us, they liked our startup and were much nicer than we expected. In fact, as we were walking off stage thinking, "Hey, that went well--maybe we'll get an interview!"--then Paul whispered something to Sam, who nodded, and they called us back.

"Okay guys. Wait, wait, come back! Come back for a second. You didn't realize that, but that was your Y Combinator interview. You're in the next batch."

And the crowd went wild...

George and I excitedly high-fived and began our flabbergasted victory dance slightly before we actually got off stage. We couldn't believe it; it had never happened before that they had decided to convert an office hour session into a YC acceptance on the spot. So now we're the first W14 YC company.

Then some more crazy stuff happened that night, and even more today, but enough about us. What does this mean for you, lovely CodeCombat player?

Right now, the server is back up and DNS is almost working again, but all multiplayer and code persistence is off. Update: both features are back now. We've also disabled Molotov Medic and a few of the dev levels we had until some bugs you found can be fixed.

In the coming weeks, we're going to fix all of the bugs and playtesting problems you all reported via reddit, Olark, email, Twitter, Facebook, Hacker News, and just talking to us at Startup School. We're also going to try to get those old levels fixed and some new ones made.

Soon after, we hope to have the level editor documented, UX-tested, and ready for action. (You can play with it right now, but you can't save, and it will be hard to understand what to do.)

We heard from dozens of developers this weekend who want to help with the project, and we love that! We are hoping to open source everything just as soon as we can, unless someone with mighty wisdom can explain why it's a bad idea. To us, openness seems completely good, and we know we can't make CodeCombat into the amazing, world-changing programming game that we want to make without your help. Thank you!

When we open-sourced everything a month ago, we were nervous. What if no one contributes?, we worried. We had spent a week writing documentation, automating the developer setup, filing easy issues, paring down the repository, and preparing licenses. We wanted to demonstrate that open source should be the default choice for many startups and games, but if we failed, then we would have done the opposite.

We needn't have worried. The CodeCombat Archmages swarmed the GitHub gates, breached the dev setup bug barricade, and presented a plethora of pull requests. Here are the first month stats:

"Okay, sure, that's a lot of contributors, but are they really helping? Those pull requests are probably tiny changes like centering some div. I bet the CodeCombat team is still doing almost all the real work and the open source thing is just for show."

Not convinced by a list of numbers? Good; I wouldn't be, either. Let's dig in and see how much the Archmages have really contributed. Here are the top five open source contributors with links to their commits:
